Diodes - Rectifiers - Arrays

30CTQ045-1 is a rectifier array device designed to provide a full-wave output with high efficiency and reliability. It is mainly used in power supply and motor control circuits.

The 30CTQ045-1 includes four ultrafast recovery rectifier diodes which are isolated from each other, making it suitable for high frequency operations. These four diodes in one package provide protection from shorts, overloads and reversed polarity to significantly reduce the risk of equipment damage. The internal diode is also designed to be low forward-voltage, achieving low power dissipation.

The key features of the 30CTQ045-1 include forward-voltage of 1V (max.), reverse-voltage of 40V (max.), avalanche-rated current of 45A (max.), reverse-power dissipation of 4W (max.), junction temperature of 175℃, and operating temperature range of -55℃ to +175℃.

The 30CTQ045-1 is designed to operate in low thermal resistance with minimum power loss and provide high rectifying efficiency. The ultrafast diode technology provides superior reverse recovery and forward characteristics. This device also provides outstanding surge capability, high-surge current withstanding capability in high frequency applications.

The 30CTQ045-1 improves the switching performance of high-frequency, high-current power supplies and voltage regulator modules (VRM) for medium to high-power applications, such as DC to DC converters, notebook computers, and LCD monitors. It can also be used in automotive applications including alternators and slew rate controllers.

The working principle of 30CTQ045-1 is simple. When the circuit is powered on, the anode of an external voltage source is connected to one side of the device and the other side is connected to the anode of a diode array. The cathode of the external voltage source is connected to the cathode of the diode array. When a positive voltage is applied to the anode, it will flow through the diode array and return to the cathode.

In the diode array, each individual diode works independently and will only allow current to pass if the applied voltage is above the forward voltage threshold of that diode. Thus, when the device is powered on, a full-wave rectified voltage will be generated on the output side, supplying a smooth DC current.

The 30CTQ045-1 is a highly efficient device that makes possible efficient and reliable power to various application fields ranging from computers, TVs and gaming consoles to telecom systems, automobiles and industrial automation. It is a versatile device ideal for use in both high frequency and power-intensive applications.
